I was just reading about the specs of Galaxy 3 on http://www.gsmarena.com/samsung_i5801_galaxy_apollo-3432.php
There was a line about memory which says:
Internal 512MB ROM, 256MB RAM
Now, in this, I understood 256 MB RAM which is the amount of memory used for running apps
But I am confused regarding 512MB ROM....what is this and what it is used for in user's context?
Think of it as internal memory-> For the ROM/FW and apps on phone (installation space)
So, I understood 256 MB RAM which is the amount of memory used for running apps
512 MB ROM is the memory used for installing apps and firmware (in other words: operating system)...correct?
Thanks for the confirmation..

Newb- ~ 1 week with new Cing-8125 - 1st handheld - it rocks
Why does "Device Info" say
RAM = 64MB
Flash = 128MB
But "Memory" shows:
Memory storage = 47.46MB
Program Total = 44.00MB
This is only 91.46MB
Is this correct ? Where's the rest?
Thanks
I am curious about this as well. According to Device Info, I should have 64MB to run programs and 128MB for storage, but I am well under that. :?
Can anyone explain what is going on???
Thanks,
Dave
You're only going to get 128 MB of ROM and 64 MB or RAM with nothing installed on the device. The ROM, which consists of the OS, the Cingular stuff, and the other included applications takes up quite a bit of storages space, about 57 MB. As for the RAM, the OS needs memory to run as well. I've installed a ton of things on my Cingular 8125 already, so I have no idea what the standard amounts are, perhaps someone would be so kind as to post them.

I understand that, but...
I would expect it to report like so:
Storage
Total: 128 MB
In Use: 38.54 MB
Free: 89.46 MB
Program
Total: 64 MB
In Use: 31.73 MB
Free: 32.27 MB
But instead I get:
Storage
Total: 47.46 MB
In Use: 38.54 MB
Free: 8.92 MB
Program
Total: 44.01 MB
In Use: 31.73 MB
Free: 12.28 MB
So what happened to 80.54 MB of ROM (Storage) & 19.99 MB of RAM (Program)? Are you saying that the base OS uses up this much RAM & ROM, and the system just shows it as not even being there? The actual image (nk.nbf) in the OS installer is 80MB in size so this does seem to add up. :wink:

I was doing a compare of Tilt vs HD2...
Are there any software tools that analyzes the actual System memory capacities? Is there really 576MB of RAM in this Tmobile HD2?

Yes there is! Actually that RAM amount is available on all the "others" HD2 (eu, au versions), you just need to unlock it with a correct combination of radio and rom..

Under device info, hw info you'll see the total quantity of RAM installed into the device while in memory settings you'll see a little less becase a part of it is used by the OS.
I hope I've been of some help.
1024 MB flash
what is it?
flash is the internal storage space but then you only hav 690.48 MB
where is the rest?
used by OS again?

the rom takes up room, so does the radio, and when the rominstalls itself (first run, or after a hard reset) that uses up more.
think of it likeinstalling your pc. you start with a nice empty disk, but by the time windows 7 has been installed it has used 6gig of space before you even run it for the first time.
I recently updated my Galaxy 3 to android 2.2 via kies (official update). Now, there is a icon for Task Manager showing which is inbuilt in 2.2
Galaxy 3 has 256 MB RAM. On the RAM Manager tab of Task Manager, it is written that 150 MB/246 MB. As far as I understand this, it means that 150 MB RAM is currently used out of total 246 MB.
My queries:
1) As per specs, it must be 256 MB but 246 MB is written in RAM Manager tab
2) On Active Apps tab of Task Manager tab, there are two apps listed with 12.23 MB and 6.53 MB RAM usage respectively, that means a total of 18.76 MB but at the same time, RAM Manager tab shows 150 MB usage. How is this possible...a bug or am i construing something wrong?
3) On RAM Manager tab, there are 2 buttons for Level 1 and Level 2 and a bar of Level 1 and Level 2. why there are 2 buttons for Level 1 and Level 2?
4) On Package tab, there is a line that says: Package Size: code + data. Program: 161 MB/194 MB. What is the meaning of this?
Note: I have not installed any app in SD card so all the memory here is phone memory
Well, level 1 is for closing inactive apps and level 2 is for closing inactive and background apps to free space

thanks for the reply. What are background apps? Can they be active apps?
Can anyone please answer this?

I can answer 2
2) The apps displayed are the running apps. There are many apps and services that run in the background and eventually consume memory. You can check that by going to setting > services and setting > manage applications> running apps. All these are running in background and will always use RAM.
4) This means that you have used 161 MB of your internal memory. It displays the total apps size
Also before you say somenthing about the low free ram space, in android phones it doesnt matter as hard as windows, here the common trend is "free ram memory is wasted memory" this because the andrioid system manage correctly the apps loaded to ram and terminates them when its needed (almost all the time), and loads.all the services you need to run, just when you feel that an app is consuming too.much or the phone.gets slow you can. Use the.inbuilt.ram.sweep, level 1 is soft sweep, it just close the active applications, for example music player if you are running music. Level 2 its a deep sweep, closing all.backgroud apps like sync, launcher etc

Answer to the 1st question:
The task manager shows "incorrect" amount of RAM because of the different calculation method. Manufacturers use an approximate value of 1000kb for 1mb, but software counts 1048kb=1mb (1024*1024 bytes). Thus 246mb*1,048=~257mb. Check wikipedia for more reference.

I was checking my phone specs on
http://pdadb.net/index.php?m=specs&id=2392&c=samsung_gt-i5801_galaxy_3__gt-i5800_galaxy_spica_2
There is a line there:
ROM_capacity: 512 MiB (accessible: 170 MiB)
I know that it has 512 MiB ROM but what is the meaning of 170 MiB accessible here?
I assume that 512 MiB is only for Android OS?

ROM is different from RAM
I assume these 170 MiB are the free space dedicated to install apps. Am I wrong ?
Yes, thats right, if im not wrong, the 512mib ROM space is used to install All the android system, leaving only 172 mb to install apps
Thanks. That means:
Total Internal Storage (ROM) = 512 MiB out of which
Storage available for android OS = 342 MiB
Storage available to install apps = 170 MiB
Total Internal Storage (ROM) = 512 MiB
It's kinda dumb to call it ROM, as it stands for Read Only Memmory. U can write/delete your ROM, including those 170MB for apps and those 342MB of OS memory with root access. Even Samsung calls it ROM...
That's what I was confused about when I first visited this forum...basically here the terminology is wrong....nothing is ROM here...and they are calling phone internal memory as ROM...
I have been using a few consecutive versions of NDT MIUI ROM successfully without many issues, however I noticed that the ROM does not seem to utilize all of the installed internal memory:
"Internal memory: 512MB (available), 767MB (total)"
(Settings -> System -> About Phone)
My device is HTC HD2 US (T-mobile) edition with 767MB RAM. I am using NDT MIUI Gingerbread-based ROM for HD2, stable release v.2.2, Androind v.2.3.5; MAGLDR version.
(Thread for the ROM : http://forum.xda-developers.com/showthread.php?t=1010498)
Have I missed or used something extra during the initial installation that limited my phone's RAM for the operating system to 512MB? (While installing MAGLDR, Clockwork Mod, etc.) If so, would anyone have a suggestion as to how I can utilize all of the RAM installed on my phone?
Strange figures, since the tmous has 1024meg ROM and 576meg RAM.
Ack, yes, my bad--my flu-affected head helped me remember the proper stats incorrectly. Yes, your numbers are correct, of course. The ROM should be 1024MB and the RAM should be 576MB. Current readings are, however:
"RAM: 512MB"
"Internal memory: 505MB (available), 767MB (total)"

I assume that the rest of the internal memory is taken up by the recovery partition? So it only shows 767 total, some of which is used by applications? Complete guess though, correct me if I'm wrong.
dunno about the ram, all android roms show 411 in my experience, (reg hd2) , as for the ROM, total available size only shows you the space allocated to the data partition, which is set to 'allsize' in the flash.cfg, meaning after the rom, cwm, boot and cache partitions have been created, whatever is left is for data, and that is the only partition the system counts towards available storage space.
Hi Guys,
I have a Defy Plus with DFP-231 Asian Retail version ROM. I had some memory cleaning widget which shows that my applications could use a total of 350 MB memory.....
I thought that the D+ came with 2 GB internal memory so I could load upto ~2GB of games(apps) running. ...:crying:
With all this confusion...
My Question is : What is the Difference between The RAM and ROM and Why is my widget showing only 350 MB usable for apps???
Kindly correct me If I'm wrong in my assumptions.
Cheers,
Vic
do not confuse ram with rom. rom is the storage which stores installed apps and system files, its like the hdd in a pc, and it keeps its content when powered down.
ram is a temporary storage from where apps run, and it clears after a power-down. (memory in a pc)
the defy has 2gb built-in storage (rom), from which 1.2 is usable for apps, and it has 512MB ram (around 470-480 usable).
you probably have a lot of apps installed, thats why the widget shows only 350mb remaining.
Thank you for clearing this

Hi, :laugh:
Thank you very much for clearing this.. So does that mean when I install apps to my phone instead of SD card they get installed in RAM and not ROM????

umm, no. they get installed in rOm, thats the permanent storage, ram is temporary. although there are solutions to install apps to sdcard. (app2sd, data2sd)

Usable for Apps means memory that can be used to store apps permanently.. It is the available ROM on your device. As stated before the 2GB memory is shared by OS & Apps.
RAM (512 MB on defy+) is temporary and is cleared on reboot and other activities.
